Letters Patent No. 77,265, dated April 28, 1868.

DRYING-APPARATUS.

TO ALL WHOM IT MAY CONCERN:

' Be it knowh that I, F. I. NORTON, of Tremcnt, in the county ofSandushy, and State of Ohio, have invented a new anduseful Improvementin Drying Lumber, Timber and the Hubs of Vehicles; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to make and use thesome, reference being bad to the accompanying drawings, forming part ofthis specification. I

4 The nature of my invention relates to improvements in apparatus fordrying lumber, and which is designed more especially for dryingwagon-hubs, but is adapted for drying other articles, made of wood, thatare perforated with holes, and it consists in an arrangement ofsteam-pipes, within a suitable building, whereby the steam is conveyedaround the interior of said building, in any desired manner, on thefloor of the same by pipes,

the said conveying-pipes beingprovided with vertically-projecting pipes,having small orifices in their tops,"

through which a very small jet of steam is allowed to escape, the hubsor other article to be dried being seton the said vertical pipes, sothat they discharge the steam into the holes through the same, as willbe more fully described on reference to the accompanying drawings, inwhich Figure 1 represents a plan view of my improved drying-apparatus,and

Figure 2 represents a section of the some on the line a: x of fig. 1.

Similar letters of reference indicate corresponding parts.

A represents the wall of the building; Bthe floor of the some, which islaid with openings between the planks, for the condensed steam to passoff through readily. 0 represents the coil of stcam-pipc,.for conveyingthe steam around the-room, from which rise the perpendicular pipes d,which are plugged at their upper' ends, and perforated with a smallorifice to admit a small jet of steam. The holes or' articles of woodhavlug holes in them are set over the said pipes, so that the steam isdischarged withiu the said holes, and first comes in contact with thewood in the central portions of the same, after which it rises andenvelopes the hubs on all sides, whereby a very uniform drying-action isofieoted,.which will prevent checking or cracking by reasonof unduestrains, as occurs when the steam or drying-medium is applied to theoutside only, as will be readily understood.

The steam may be supplied from a boiler under thefloor, or from anyother convenient arrangement.

Another advantage of discharging the steam directly against the surfaceof the wood is, that while it utilizes that which is discharged, itpermits a circulation to be kept up through the pipes, maintaining theheat. at a uniform temperature.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is I An apparatus, substantially as described,for discharging steam into the central openings ofwagonhub, and othersimilar perforated articles of wood, for drying the same, as and for thepurpose described.

2. The combination of the steam-coil G and verticaejectingrpipes d,substantially as and fcrthe purposedescribed.

The combination, with a drying-chamber, A B, of the steam-pipes G d,substantially as and for the purpose described.

The above specification of my invention signed by me, this 21st day ofFebruary, 1868.
